The first time you run iOLab on a new computer, it is important to calibrate your device's force probe and accelerometer.
In the top toolbar of your iOLab application, click the Reset button twice.
Select "Calibration" in tools menu
Click the gear icon to open the tools menu. Select Calibration, then select Accel - magn - gyro for the remote you want to calibrate. Follow the on-screen instructions to calibrate the device. Then, do the same for the force probe by selecting Calibration, then Force.
